  • International Organization for Standardization (ISO) Mine Closure and Reclamation Terminology Mine Closure and Reclamation Management Planning

    These two projects are under the technical committee of Mine Closure and Reclamation Management. The target of these developing projects is to provide standards regarding mine closure and reclamation management to minimize the impacts caused by mines during the closure lifecycle (exploration, extraction, suspension of operation, mine closure, reclamation, and follow-up management). The aim is to re-establish mine closure planning at every stage for sustainable resource development and risk management; however, these standards are likely to exclude safety and health issues related to workplace activity.

  • International Organization for Standardization (ISO) Environmental Management Systems – ISO 14001:2015

    This standard sets out the requirements for an environmental management system, by helping organizations identify, manage, monitor and control their environmental issues in a holistic manner. This standard includes the need for organizations to be continually improving their management systems and environmental concerns. Some of the key elements this standard requires are a greater commitment from leadership, implementation of proactive actions, a focus of the entire life cycle, a stakeholder-focused communication strategy and ultimately for environmental management to become a greater priority within the organization. This standard can be used by any organization and once adopted, an independent certification body would audit the practices against those of the standard and if cleared they can become ISO 14001 certified. Adopting such a standard and specifically becoming certified has proven to be beneficial for mining organizations given that it reduces environmental risks and liability, improves awareness, creates cost savings and lowers insurance cost.

  • UN Environment & GRID – Arendal Mine Tailings Storage: Safety Is No Accident

    This report has been developed to encourage targeted action at the policy and technical level to make zero catastrophic incidents become a reality and ensure that economic prosperity is fully compatible with community health and safety. In doing so, the report makes two central recommendations, the first being to take a safety-first approach in management actions and on the ground operations. The second is to establish a UN Environment stakeholder forum to facilitate the international strengthening of tailings dam regulations. It also identifies three actions to improve regulation and practice: facilitate international cooperation on mining regulation and the safe storage of mine tailings through a knowledge hub, failure prevention and crisis response. In addition, the report discusses how mining firms can adopt cleaner processes, new technologies and re-use materials in order to reduce waste. The two technological advances discussed are bioleaching and smart sensors for monitoring.
